Antonio D'Antoni (25 June 1801 – 18 August 1859) was an Italian opera composer and conductor.
D'Antoni was born in Palermo to a musical family and gained local fame when in 1813, at the age of 12, he conducted his own composition, a Mass for St. Cecilia's Day.
A friend of Meyerbeer, Bellini, and Donizetti, D'Antoni worked in England, Frankfurt, Venice, and Florence before settling in Trieste.
[2] In 1828, he became the music director of Trieste's newly formed Società Filarmonico-Drammatica (Philharmonic and Dramatic Society).
He composed four operas, the first of which, Un duello (A Duel), premiered at the Teatro Carolino [it] in Palermo in 1817.
